I wrote an Android App last year that I felt I needed myself when I was out and about in the field photographing long exposures. I’m happy that it has now more than 2000 active installs and I have taken all comments into account and released an updated version.
As you are well aware of, most films do need correction of the exposure time for reciprocity failure to avoid underexposing your negatives for exposure times of over a few seconds. This really gets important for night photography, when using filters and for Large Format or pinhole photography. All information is contained in the App so no data connection is needed when you’re on a photo shoot abroad, on top of a mountain or in the deep countryside without any connectivity.
I do not miss the folder with printed and weather-beaten PDFs with tables of exposure correction information for the different films that I had to rely on before. 🙂
The Reciprocity App has the following features:
- Easy to use and usable on Android devices of most sizes.
- Lots of B&W, colour and slide film included in the App, and this list is growing with every update.
- Include filter factors in the exposure time calculation.
- Include bellows extension in the exposure time calculation.
- Built-in timer to use the calculated exposure.

Details about the calculation:
In addition to the film manufacturer supplied reciprocity information, I used the findings of Howard Bond from his article in the Photo Technique magazine which had been formulated into an easy formula by Patrick Gainer.
It is a simple App, but packed with the reciprocity details of most black and white films currently being sold and a growing number of colour and slide films. Works fine on new and old Android phones as well as on Android tablets.
It’s free, make sure to grab it!
The 33 temples of the Bandō Sanjūsankasho (“The Bando 33 Kannon Pilgrimage”) form together with the 33 temples of the Saigoku pilgrimage and the 34 temples of the Chichibu Kannon temple pilgrimage, a 100-temple Kannon pilgrimage.
Now free Android apps for all three of these pilgrimages are available from the Android store.
Of the three pilgrimages, at a mere length of 100 km, the Chichibu 34 Kannon pilgrimage is best suited for the tourist who can only dedicate a limited amount of time and would like to walk the pilgrimage. And as Chichibu is, undeservedly, still largely undiscovered by the majority of the tourists, you have a chance to enjoy a lovely area of Japan that is less than an hour from Tokyo by train.

The pages describing my experience of walking the Chichibu 34 Kannon temple pilgrimage on this blog remain popular and this makes me happy as that means that a lot of people are looking to get more out of their trips to Japan, decided to get out of the big cities and get a taste of the real Japan. I’m therefore happy to announce that I’ve written a free Android App that works as the perfect travel assistant specific for the Chichibu 34 Kannon Temples pilgrimage.
The Henro App is based on my own experience walking the pilgrimage and it is what I would have liked to have with me when I was doing the pilgrimage. Some of the temples are difficult to find. Even though there are some signs and stone markers guiding the pilgrim, especially in the Yokoze area, I found myself walking with both the books in my hand constantly looking at hand-drawn maps that were put together a long time ago and not always accurate or reading descriptions that were a bit confusing at times. I really felt like I wanted to have all the details of a temple and up-to-date maps easily accessible on my phone or tablet and even have the possibility to use GPS to indicate your current location or use for navigation to a temple.
Well, here it is is, a perfect pilgrim’s assistant and I have packed it with loads of details about other tourist attractions in Chichibu as well; so even if you don’t use it to do the pilgrimage, you’ll get plenty out of it when you visit Chichibu and it comes at a price you cannot beat. Available now in both English and Japanese (日本語版). 🙂
